to change anything, go back to step #1.
Adjusting the Relative Humidity “SETPOINT”
TheDEH3000/Rsensestheambientrelativehumidity(%RH)ofthe
spaceinwhichitislocated.Itcomesfactorypresettohold50%
relative humidity.
Therelativehumidity“SETPOINT”(desiredRHtobemaintained)operates
thedehumidierfunctionoftheUltra-Airedehumidier.Ithasnoeecton
theoptionalVENT(freshairventilation)orFAN(householdairrecirculation)
functions if they are being used.
Thestandardrangethatthedehumidierholdsaroundyour“SETPOINT”
is3%.Withasetpointof50%,thedehumidierwillrununtiltherelative
humidityreaches47%.Thedehumidierwillthenswitchountiltherelative
humidityreaches53%.
Ifthesetpointishigherthantheambientrelativehumidity,thespacedoesnotneedtobedehumidied,
sothedehumidierwillnotrun.
Example:Setpoint:50%RH
Currentcondition:45%RH–Thedehumidierwillbeo(no“O”indicatorwillbedisplayed).
Ifyoursetpointisbelowtheambientcondition,thedehumidierwillbeonand“O”willdisplay.
Example:Setpoint:50%RH
Currentcondition:55%RH–Thedehumidierwillbeon(“O”displayed).
Temperature Cutout Programming
Dehumidiersproduceheatwhendehumidifyinganddependinguponoutsideconditions,theventilation
function may also introduce warm air. Some conditions may introduce enough heat to drive household
temperaturesup.TheDEH3000/RtemperaturecutoutfeaturedisablesallUltra-Aireoperationsifhousehold
temperatures reach the cutout setpoint.
Inmostinstallationsthisfeaturewillnotneedtobeused(thecutoutisfactorysetto99°F).Ifalower

REMOTE SENSOR OPTION
The remote sensing option is used when an installation requires mounting the DEH 3000 out of the
conditioned space or when it is desired to specically monitor and control the conditions at a particular
location in a larger conditioned space.
Both the need for and location of the remote sensor should be determined by a heating/cooling
professional. In most installations, the onboard sensor in the DEH 3000 will be sufcient to monitor and
control the conditioned space.
Install and Wiring Instructions
Routing Signal Wires
You will be required to supply and route 24 gauge, 4 conductor solid wire (2-line telephone wire) between
the DEH 3000R controller and the remote sensor location. The wiring run should be no longer than 100 ft.
Avoid routing this interconnect wire parallel to high voltage wiring. Maintain a distance of 2 ft. or more from
high voltage lines.
Sensor Connection
The sensor can be mounted to a wall or ceiling surface. Ideal sensor location is 5 ft. above the oor. Wires
should exit through a ½” diameter hole in the mounting surface at the mounting location. Use the provided
splice connectors to connect the 4 wires from the remote sensor to the user-supplied interconnect wire. Be
sure to keep proper colors attached to each other.
Sensor Mounting
You will need two screws to mount the sensor. Use the two slotted holes to mount the base of the sensor to
the wall and then snap the cover into place.
Controller Connection
Use the provided splice connectors to connect the 4 wires from the DEH 3000R to the user-supplied
interconnect wire. Be sure to keep the proper colors attached to each other.
Continue with the installation as described in the rest of this manual.
This section is applicable only to customers who have purchased a remote sensor package.
The standard DEH 3000 controller does not offer remote functionality.
WARNING!
THE USE OF SPRAY PAINT ON THE SENSOR HOUSING MAY DAMAGE THE SENSOR AND IS
NOT COVERED BY THE PRODUCT WARRANTY.
